Two clocks run at once in a moulding business
The first clock is the development clock. A new part or pack takes months to reach production: design freeze, tool manufacture, a T0 trial that never quite works, a correction, a T1 trial, sample submission, and finally approval. Nothing is sold during any of it, and the customer's launch date does not move.
The second clock is the polymer clock. Resin prices move with crude, import parity and freight, and they can move meaningfully between the day a quote is issued and the day it is accepted. A business that manages the first clock badly loses programmes. A business that manages the second badly wins orders it should have declined.
